Some bits are slightly different on a4xx. Use the encodings that work.
Perhaps these can be combined at some point if we get a proper

This is necessary for some ops which have slightly different encoding on
a4xx/a5xx, but are otherwise identical. This helps keeping the compiler
from having to worry about these details and creating separate ops.

Fix defect reported by Coverity Scan.
Unintentional integer overflow (OVERFLOW_BEFORE_WIDEN)
overflow_before_widen: Potentially overflowing expression 2 << W
with type int (32 bits, signed) is evaluated using 32-bit
arithmetic, and then used in a context that expects an expression
of type uint64_t (64 bits, unsigned).

We can see from the dynamically_uniform (compiler doesn't know if you're
uniform or not) vs uniform (compiler can see it's uniform) case in the
blob which is which. Now that we have the right names, also use the
nonunif flag for encoding the actual non-uniform mode (previously, we were
always setting it always in a way that meant uniform).
I verified this behavior back to a418 with samplers. The a3xx blob I have
only does GLES3, so we don't have the opaque_type_indexing tests to see.

We were treating them the same as regular cat2/cat3/cat4 immediates, but
that's not right because cat6 sources are only 8 bits.
Our bindless code was handling this before for bindless resources, and
it was disabled for most other things, so this was mostly harmless, but
fixing it will be necessary for handling ldc offsets.
In addition enable tests for this that were just commented out, and add
a custom test making sure that the immediate source is treated as
unsigned.

Example of blob's output:

It does: (src2 << src1) | src2
src1 and src2 could be GPRs, relative GPRs, relative consts,
or immidiates. However, they could not be plain const registers.

MOVMSK is a bit of a special case, because it takes multiple cycles (and
therefore reduces the nops needed if it's between some other assigner
and consumer) however weird things happen if you try to start reading
the first component while it isn't finished yet. On balance making it
use repeat seems to result in a fewer special cases.

The full form for ldg.a/stg.a offset is:
g[reg_address + reg_offset << (imm_shift + 2) + imm_offset << 2]
where imm_shift is in [0, 3] and imm_offset is in [0, 3]
a6xx blob was found to produce a bit simplier offset calculations
for TES/TCS shaders in GTA V:
[c002000a_03c14215] ldg.a.f32 r2.z, g[r1.y+((r2.z+1)<<2)], 3;
[c0020004_01c14609] ldg.a.f32 r1.x, g[r1.y+((r1.x+3)<<2)], 1;
Our new syntax:
stg.a.u32 g[r2.x+(r1.x+1)<<2], r5.x, 1
stg.a.u32 g[r2.x+r1.x<<4+3<<2], r5.x, 1
ldg.a.f32 r1.w, g[r1.y+(r1.w+1)<<2], 3
ldg.a.f32 r1.w, g[r1.y+r1.w<<5+2<<2], 3

The "demote" intrinsic has the semantics of D3D discard, which means
it doesn't change the control flow, allowing derivatives to work.
On A6xx there is no known way to check whether invocation was demoted,
thus we use nir_lower_is_helper_invocation.
Add "logical" OPC_DEMOTE which is later translated to "kill".
Such separation is necessary to run "kill" specific optimizations
which are invalid for "demote".
